' I OE DAYTON, OHIO, A CORPORATION OF DELAWARE REFRIGERA'IING APPARATUS Application filed October 30, 1928. Serial No. 316,099.

This invention relates to refrigerating apparatus and more particularly to a cabinet adapted to have inserted therein a cooling unit of a mechanical refrigerating system.

An object of this invention is to provide a cabinet having metal panels with adjacent and parallel edges spaced by a metallic spacer provided with resilient parts.

Another object of this invention is to prol'olvide a cabinet of the type hereinbefore described in which the metallic spacer is provided with an integral enlarged metallic head for aiding in looking the spacer between the panels.

Another Object of this invention is to provide a cabinet with panels having adjacent and parallel edges spaced by a metal spacer provided with rubber facing against which the porcelain panels abut.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of the present invention is 25 clearly shown.

In the drawings:

Fig. 1 is a view in perspective of a cabinet embodying features of this invention;

Fig. 2 is an enlarged cross sectional view 30 taken along the line 22 of Fig. 1;

Fig. 3 is a side elevation of a metal spacer embodying features of this invention;

Fig. 4 is an enlarged cross sectional view taken alongthe line 4-4 of Fig. 3;

Fig. 5 is a view similar to Fig. 3 of a modified form;

Fig. 6 is an enlarged cross sectional view taken along the line 6-6 of Fig. 5;

Fig. 7 is a side elevation of a spacer adapted to be used adjacent the door openingof the cabinet; and

Fig. 8 is an enlarged cross sectional view taken along the line 8-8 of Fig. 7.

A cabinet embodying features of this in- 45 vention is generally designated as 20. It may include an insulated food compartment behind the doors 21, which compartment is adapted to receive the cooling unit of a me-' chanical refrigerating system. The cabinet .may have panels with adjacent and parallel edges. Thus in this particular embodiment, the cabinet may include side panels 22, front corner panels 23, an upper door j amb panel 24 and a lower door jamb panel 25. Any or all of these panels may have adjacent and parallel edges. A cabinet adapted to have features of this invention embodied therein is disclosed in the application of Henry P. Brauetigam and William C. Holbrook, S/N 257,589 filed February 29, 1928, to which reference is made, if necessary, for a further description of the cabinet.

The cabinet may include a framework. Thus as shown in Fig. 2, the framework may include corner upright members dovetailing into horizontal corner members 31 and- 32. Members 30 and 32 may form part of the door jamb of the refrigerator. To this framework the lining of the food compartment together with its insulation may be attached. Also to this framework the outer casing including panels 22 to 25 inclusive may also be attached. If desired, cushioning material 33 and 34, such as wall board or card board may be interposed between the outer panels and the frame or the insulation of the cabinet. The panels 22 and 23 may be secured to the framework by screws 35 at the lower and upper edges of the panels. Since a top 36 is provided with downwardly directed flanges which telescope over the upper edges of these panels the screws at the upper (Edges of panels 22 and 23 are not shown in This construction produces adjacent and parallel edges. Thus the edge of the panel 22 is adjacent and parallel to the edge 41 of the panel 23. 'The edge 42 of the panel 23 is adjacent and parallel to the edge 43 of the panel 24. Flanges may also be provided at the edges. Thus the edge 40 ma be provided with an. inwardly directed ange 44. The edge 41 may be provided with an inwardly directed flange 45. The edge 42 may be provided with an inwardly directed S- shaped flange 46. The edge 43 ma be provided with an inwardly directed ange 47. A metal spacer having resilient parts ma be interposed between the adjacent edges 0 the panels. Thus the spacer may be interposed between the edges 40 and 41 and the sgacer 5,1 may be interposed between the e ges 42 and 43. The spacer 50 may be a long metal strip of the typeshown in Figs. 3 to 6 inclusive. The spacer is adapted to have a portion placed around one of the edges and is provided with an integral head adapted to lock the spacer between the edges. In Figs. 3 and 4 the spacer may be an angularly cross sectioned metal strip 60 having legs 61 and 62. The leg 61 may be provided with an integral head 63 which, in this embodiment,

' is formed by bending the metal strip upon itself to form the head as shown in Fig. 4. The leg 61 may be provided with open ngs 64, and rubber may be moulded on the sldes of the leg 61 and is held in place by allowing which are adapted to lock the spacers between the panels. The spacers are thus angularly cross sectioned at 76, and in this partiipulafi' embodiment the angle is in the form 0 a a i The spacers to be placed between the panels 24 or 25 and the panels 23 are relatively short. In this particular, embodiment,

the metal spacer may formthe head 70. An

angularly cross sectioned rubber piece may be embedded and pinched in the head 7 0, and may be provided with legs 71 and 72 to'form an angularly cross sectioned spacer. If desired, reinforcement may also be provided. Thus the cloth strips 73 and 74 may be embedded inthe legs 71 and 72. As shown the strips are embedded-at the center of the legs, but they may be embedded in any part from the edges of the legs to the center. The head may be provided at its ends with backwardly bent portions 75 adapted to fit around the door jamb opening. The rubber portion comprising the legs 71 and 72 may be placed around the flange 47 and the spacer thus formed may be interposed between either of the panels 24 or 25 and the panels 23.

Any or all of these panels may be removed independently from the others. Thus the panel 22 may be removed by loosening the screws 35 and swinging outwardly the rear edge of the panel a slight distance after which the edge 40 with the flan e 44 maybe removed from the notch an the framework. The panel 23 may be removed also by unloosening the screws 35 and by swinging the panels slightly about the pivot formed by the flange 46, after which the panel may be removed from the notches 80 and 81. The panels 24 or 25 may be removed by withdrawing nails placed in flanges, not shown, along the longitudinal edges of the panels, as more clearly disclosed in the application of S/N 257 ,589, heretofore referred to.

When thecabinet is provided with a central door mullion, a panel 83 may be placed over the mullion. The end edges of this panel may be provided with flanges, not shown, which are adjacent and parallel to the side flanges, not shown, of the side panels 24 and 25. Spacers 51 similar to spacers shown in Figs. 7 and 8 may be interposed at these points also. The construction of the panels is more clearly disclosed in the application of S/N 257,589 heretofore referred to.

While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What is claimed is as follows:

1. An insulated refrigerator cabinet having metal panels with adjacent and parallel edges, an angularly cross sectional metal spacer fitting around one of said edges and having a portion between said panels, said portion having an enlarged integral head, and said spacer being provided with rubber cushioning means adjacent said edges.

2. An insulated refrigerator cabinet having metal panels with adjacent and parallel edges, a U-shaped metal spacer fitting around one of said edges and having a portion between said panels, said portion having an enlarged integral head, and said spacer being rovided with rubber cushioning means ad-- jacent said edges.

3. An insulated refrigerator cabinet having metal panels with adjacent and parallel edges, an angularly cross sectional spacer fitting around one of said edges and having a portion between said panels, said portion having an enlarged integral head, and said spacer being provided with rubber cushioning means moulded on said spacer adjacent said edges.

4. An insulated refrigerator cabinet having metal panels with adjacent and parallel edges, a U-shaped metal spacer fitting around one of said edges and having a portion between said panels, said portion having an enlarged integral head, and said spacer being provided with rubbercushioning means moulded on said spacer adjacent said edges.

In testimony whereof I hereto aflix my signature.
